2, 4, 8, or 16 RS-232
serial ports, sup-
porting data rates up
to 115.2 kbps.
Available in three
hassis: standalone
(with DB25 RS-232
ports), standalone
(with RJ-45 RS-232
ports), or ra kmount
(with RJ-45 RS-232
ports).
Instant onne tion to
10-Mbps Ethernet.
Compatible with all
known varieties of
UNIX®, plus WINS
support for Windows
environments.

terminal servers that still “don’t
do” TCP/IP and have no cl e how
to talk to yo r UNIX comp ters?
O r Enhanced TCP/IP
Terminal Servers are ready for
yo r network. They come in two
8- or 16-port varieties and one 2-
or 4-port variety. The standalone
8- or 16-port version has reg lar
DB25 female RS-232 connectors
(pinned as DTE). The rackmo nt
8- or 16-port version has RS-232
RJ-45 sockets. The standalone
2- or 4-port version has RS-232
RJ-45 sockets. (Both DB25 and
RJ-45 ports carry all signals
necessary for f ll modem control;
less expensive, more flexible
twisted-pair cable can be sed
with the RJ-45 port.) These ports
can be set for any standard data
format or flow-control option and
for most standard async data
rates from 50 bps to 115.2 kbps.
Yo can attach a network
cable to any one (b t only one) of

instant connectivity to
your UNIX hosts.
KeyFeatures
ENHANCEDTCP/IPTERMINALSERVERS
the 8- or 16-port Terminal Server’s
three Ethernet ports (AUI,
ThinNet, or 10BASE-T); it will
a tosense the connection and
establish its network presence
immediately.
The Terminal Servers are
compatible with every type of
UNIX we’ve tested them with,
incl ding Lin x®, SCO®UNIX and
Gemini®, AIX®, Solaris®, HP-UX®,
DG/UX®, BSD®, IRIX®, and Citrix®
Winframe®. All models are also
compatible with Windows®3.x, 95,
98, Windows NT®, and Windows
2000, tho gh some of their
important feat res (s ch as TFTP
and dial-o t socket connections)
are not yet available nder
Windows.
Whatever yo want to do with
TCP/IP, the servers most likely will
handle the protocol. They operate
with Telnet™ and rlogin for
session control; PPP, SLIP, and
CSLIP for modem and remote-
access s pport; lpd and rcp for
printer s pport; ARP and BOOTP
for network-based set p; DNS for
internetworking s pport; and
gateway tables for IP-ro ting
s pport, among others. The
servers also f lly s pport SNMP,
and they come with proprietary
software that incl des tilities
that extend modem and printer
s pport, add “fixed tty” s pport
for terminals, and process
proprietary SNMP variables.
The servers have a pop- p
men system (with on-screen
help) that can appear in m ltiple
terminals and in any of five
lang ages (English, French,
Spanish, German, or Italian).
Sec rity’s ass red. The nits
s pport s pervisor and port
passwords; port locking;
a thentication (incl ding PAP);
ser access profiles; logging for
service, a dit, and billing; and
modem a to-reset.
